When used as text against a white background, it may not meet WCAG (Web Content Accessibility Guidelines) standards for normal text. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Using a color contrast checker is crucial to ensure sufficient contrast.

Thoughtful consideration of color combinations and contrast ratios is essential for creating inclusive and accessible designs.
